Montana Agate is a gemstone found in Montana, USA. Agate is a densely packed fine quartz formed by the depositing of multiple layers over many years in small cavities in volcanic rock. Beloved as a talisman or amulet since the ancient times of Mesopotamian and Egyptian civilizations, agates are found all over the world, including Japan, and its colors and patterns vary widely depending the area. Among them, Montana agate often contains red iron oxide and black manganese oxide, characterized by the unique appearance of rhythmical patterns reminiscent of smeared dots of ink dabbed with a brush, like an abstract painting. The agate we have carefully selected for this piece features a rhythmic black pattern as if painted on the milky white canvas of an abstract painting, the contrast that changes with each layer giving it a sense of depth. The gold ring has a matte texture with traces of handiwork for a sense of warmth, in a simple design like the frame of a painting, in harmony with the rounded glossy form of the Montana agate. A bold ring with an eye-catching presence.
